摘要: 浑善达克沙地是内蒙古自治区境内距北京市最近的沙源地,其生态环境的变化严重影响当地及京津地区的发展。通过对比分析2001年与2015年浑善达克沙地所在地区的自然环境概况、社会经济特性和生态环境的变化状况,研究该地区近年来生态状况,分析气候变化趋势、生态系统组分构成、经济产业发展情况以及荒漠化面积变化趋势,探讨引发该地区生态环境变化的原因。结果表明,浑善达克沙地气温和降水量的变化对于该地区生态环境的影响较小;牲畜数量呈下降趋势,荒漠化程度不断降低,生态环境正逐步得到改善;第一产业产出长期维持在同一水平上。近年来,虽然生态环境状况出现好转,但仍不可忽视恶化地区,还应不断加强全民生态意识,继续推进禁牧、造林等治理措施。

Abstract: Hunshandake sandland becoming one of the main sand and dust sources in Beijing and Tianjin region, and it threatened the social, economic sustainable development and ecological security around Beijing, Tianjin and north China. The natural environment, socio-economic characteristics and ecological environment of the Hunshandake sandland in 2001 and 2015 were compared, and the ecological status, climate change trends, and components of ecosystem components were analyzed to explore the causes of changes in the ecological environment in this region. The results showed that changes in temperature and precipitation in the Hunshandake sandland have less impact on the ecological environment of the area. Additionally, the number of livestock has shown a downward trend, the degree of desertification has been decreasing, and the ecological environment is improving gradually. Finally, the output of the primary industry was maintained at the same level for a long time. In recent years, although the ecological environment has improved, but still cannot be neglected the deteriorating areas. People must be increase the ecological awareness continuously, and continue to promote governance measures such as grazing prohibition and afforestation.

Key words: Hunshandake sandland, ecological environment, ecological system, desertification
